To 1N 'autom it wif/13! concer/1L:

- it known that l, EDWIN R. Mnunnm a ei een, oi the United States olf America, i'esiding :it Detroit., in tlie county el' lleyne :unl Stute of lllicliigon, lleve invented oei'- tziin new anti useful improvements in Der mountable Runs, oi.1 which the following is :i specicetion, reference being lied therein to the accompanying drawings.

invention relates to cleniounteloie time ont?, consists in the provision of o novel construction of demountable fini 'whereby the tire may loe readily detachecl 'from the rim Without removing' tlie latter from. the telly, or' the tire and rim be mounted os e unit.

The invention resides in the "peculiar construction, arrangement enti combination of 'ports es Will more fully llercinaftei appear anni es particularly pointed out in the claim.

ln the lmivingsf- Figure l is en elevation of e 'wheel ernbodying my invention;

Fig. 2 is :in edge elevation of 'the 'fini of :L tire detached;

3 is a. section on the line afi-a2 Fig. l; y

Big. 4 is e bottom pien view illustrating the locking iievice; end' Fig. 5 is a fregnientzny perspective view, looking from the top.

ln automobiles it is quite oustoiney to carry en eXtra tire upon a clemountzilole rim with the tire inflated in readiness for use. However. it is necessary frequently to detach the tire from the i'im for repairs or the like and then replace it, but in the usuel construction of demonntolile rim, While the engaging sind clisengeging; off the rim with the Wheel felliT mov lie readily peiiiomnecl, if the tire is to be eletochecl from the rim it is necessaryI to rst ielnove the rim from the Wheel and then fletnclf ille tire.

With my improved constmetion not only may the rim and tire oeiezulilv tleinounted from tlie felly as e unitbut also *elle tire may loe `detached from tlle i'im While the letter is igirlily clamped to the ifelly. The tire therefore, may loe much moire quickly and easily removetl than in structures Where the rim must first be cleinountecl.

As slioivn, A designates 'the rim, herein illustiatecl of the clencliei type, compose@ oi a lease B and spacecl tire-engaging bearings ,ing accidentel ER the section being integfelyivitli the remaining segmental portion of the 'rimi' and the section l? -lieing' letefelly displace able in relation to tlie ethos sectionr unil eeirying e, segment of tlie annuler flange C. Pi'eferably tlie section l? is mounted upon 'nis Gf rigidly connected to the bottom fece ereof es by .rivets H enel these arms are pivote@ et I to theuneisicle of the bese of tlie segmental portion il. This permits the section F to be movecl sway from the section E and the length of the adjustable portion is suoli es to allow the tire to be readily ielnoveil when the section F is acliustecl to the position shown in flottecl lines in Fig.

The sections@ Vend ll may oe locked to getlier in their operative positions in any suitable manner, but I have shown herein e novel :incl simple locking device which may be easily opel-ated and does not require a special tool to loe employed. Thus one of the sections es F is providecl with e lug o1 pin J adopted to loe engaged by a slotted portion K of en arm L that is pivotel to the 'other section. The connection between the eine and its respective section is formed bv e pin M cost ntegi'nl with the erm and pivote ily engaging an aperture N` in the lastmentionefi section. The outer enel of the pin is riveted, Welded or the like to e Washer El", and when the tire is inateol it will exert pressure .upon the Washer suiiioient to prevent the latter from turning, thereby avoidclisenejsgement oi the slotted portion from the pin, and 'also preventing rattling of the looking aim.

xwhen the tire is in engagement With the rim and tlie complementary sections E F locked together, the rim may 'be attached to the iellv in the usuel manner es lov means of spaced clips O, or (lemountecl from tlie felljv liv releasing* tlie clips. When the rim is upon the fellv the locking; devices and also the arms G lie in the space? oetveen the losse of tlle :rim :incl the telly. ln ease tlie tire is to te remove@ from the rim While tlie latter is on the telly, it is merely necesserv to insert :i suitable tool in tlie szoaee P enel move the locking members foi' tlie seetions to en inoperative vposition, enel to re .lesse the locking nient with tlie portion of the segmental flange (l that is earriezi by tlie adjustable section. Tile letter may tix/en be movecl to tile position shown in lottecl linee in lig. 2

and the tire detached from the rim. The remaining locking clips O 'will rigidly secure the rim to the fell While I have shown and described the. preferred Aform ofmy improvement, I do not desire to limit the protection t0 the exact. eonstrction illustrated, as I believe the structure susceptible to various 'changes ivithout departing from the scope of my invention..

' What I claim asV my invention is The combination with a two-part' rim, of

' a pin and a hook for engaging said pin re- =petively moilnted upon the inner faces of the rim members, a pivot pin rigidly. con- 15 nected 4with the'hook member and passing through thev correlated riIn member, and a washer mounted fast upon `said pin adjacent the exterior face of the rim, whereby the pressure of a tire carried by the rim acts to 20 prevent motion of the hook. In testimonyy whereof, I aHiX my signature in 'presence of two Witnesses.
